As far as I know (and I the physical issues to prove it), PC Gamer didn't begin numbering their CDs until #150, July 2006. The June 2006 issue had the key #7.67 on both the disc and the magazine's spine.
So, if anyone could scan the sleeve or their discs to clarify this matter, it would really help us all here. I don't think the disc images included here are really from the January 2005 issue because I own that one and there only was 1 CD included, not two. Perhaps this is from the January 2006 issue, at least that one included 2 discs.
If anyone can help...
